Most commercially available shampoo formulations use synthetic surfactants, which can cause allergies, irritation, and negative environmental effects.Writing in progress process, Scientists at a Brazilian research institute report that three plant-based surfactants may offer natural alternatives in shampoo formulations.
“The development of cosmetic formulations using plant-derived biosurfactants is promising and represents an alternative to cosmetics formulated solely with synthetic surfactants,” the authors write.
The three surfactant-rich extracts are Pigweed Quinoa (Quinoa), Glycine Max (soybean),and Malpighia emalginata(Acerola cherry). Seeds of C. quinoa and G. max were powdered and extracted. The fruit of M. emarginata was made into flour and extracted.

The authors analyzed the properties of these extracts alone and in formulations to determine their potential to replace or reduce the amount of synthetic surfactants in shampoos.
Each extract was analyzed for stability, antioxidant capacity, irritation, detergency, and toxicity potential. The authors created a total of seven shampoo formulations using the three extracts to measure surface tension and interfacial tension reduction.
For comparison, seven shampoo formulations were tested side-by-side with a commercially available moisturizing shampoo. The authors tested a variety of factors, from pH to soil dispersion to cleaning ability.
All remained stable within the temperature and pH range. G.maxand C. Quinoashowed low toxicity and no toxicity, respectively. The pH range during stability testing was within the normal range for those commonly used in cosmetic formulations. M. emalginatashowed the highest antioxidant activity and could potentially be marketed as a multifunctional additive. All extracts were classified as less irritating than sodium lauryl sulfate, a common surfactant in shampoos.
All formulations, especially those combined with 10% disodium cocoyl glutamate, showed similar sebum removal ability as commercial shampoos.
For the shampoo formulations, F1 contained no surfactant, F2 contained 4% DCG, and the other formulations combined 10% primary surfactant and 4% DCG as secondary surfactant. Contains things.
All shampoos tested had acceptable surface tension, density, foam formation and soil dispersion. When it comes to cleaning ability, DCG and three shampoos stood out. M. emalginata,DCG, G. Max,DCG, C. Quinoaand G.max. Shampoos that used only DCG as a surfactant produced less sebum than the combination, meaning that the plant extracts helped improve cleaning power.
“This study shows that it is possible to formulate shampoos with lower concentrations of synthetic surfactants than current practice, and that plant-based surfactants have suitable properties to provide superior natural alternatives. ,” the authors write. “Five of the manufactured formulations (F4, F5, F6, F7, and F8) are subject to subsequent quality control testing and may become commercial formulations…”
